Review on Ultimate Storage Solution: Nalgene Transparent Lexan Square Storage Bottle by Jason Winkfield

I bought this to use cream for making coffee. I've tried several different containers and Lexan seems to work best for storing cream. Easy to clean and I prefer the clear Nalgene bottle. I also plan to use the 4 ounce version of this to store my balsamic vinegar when I go out to eat. I have a favorite vinegar, so I always carry it with me when I use it. I would like someone to suggest a 500ml bottle - seems odd, I can buy 1L, 250ml but not 500ml.
